Section 4
Guardianf
Slime is a leading cause of ice machine breakdowns and
biological growth is a health concern. The Guardianf
system releases chlorine dioxide on a controlled basis to
inhibit the growth of bacteria and fungi that form slime
and cause malodors in the food zone of ice machines.
The Guardianf will not control mineral or other water
borne buildup. Your water quality will determine the
length of time before mineral buildup affects ice machine
performance. Mineral buildup must be removed as often
as necessary to ensure trouble-free operation of the ice
machine.
The Guardianf sachet holder is included with the sachet
packets. Refer to installation/replacement procedure to
install/change sachet holder/ packet.
